City of Willits Groundwater Resiliency Improvements Project

City of Willits Groundwater Resiliency Improvements Project

The City of Willits (City) proposes improvements to the existing Willits Groundwater System in order to increase the City’s conjunctive use capabilities and provide the City with a reliable water supply sufficient to meet community needs in the event surface water becomes untenable. The proposed project would provide the City with the flexibility to manage water sources adaptively, considering factors such as aquifer and watershed health, water quality, operational constraints, and ecosystem health. The proposed project is located northeast of the City center on City-owned parcels identified by APNs 007-010-01, 108-030-06, and 108-020-05 (Site), which are currently utilized for the Willits Groundwater System, including the Elias Replacement well, Long 20 test well, and groundwater treatment plant, and located adjacent to the City's sewer plant. Improvements include the installation of 3,750 feet of new water line and the abandonment of 3,600 feet of existing water line within the Willits Groundwater System, upgrades to the pumps of the Elias Replacement well and Long 20 test well, arsenic pilot testing on the Long 20 test well, and the installation of a 250,000-gallon clear well adjacent to the west of the groundwater treatment plant, to be completed in three (3) phases.
